這是我的 manage.py 文件：在此處輸入圖像描述

Answer 1

在錯誤消息中，它說您需要一個字符串而不是“PosixPath”嘗試將路徑轉換為字符串。

Answer 2

您還可以使用：

DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        }
    }

Answer 3

您可以簡單地嘗試這種方式：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

在settings.py文件中添加以上代碼后，首先需要刪除db文件並刪除每個應用程序的所有migration folders ，然后運行以下命令：

python manage.py makemigrations appname

python manage.py sqlmigrate appname 0001

python manage.py migrate

現在您的問題將解決。
